Wart treatment question

[Thomas Ashcraft]

Maybe someone could help me in this newsgroup.

While I was a student at McGill University in 1975, I participated 
in a "wart clinic" at one of the Montreal hospitals. I had had 
persistent warts on my hands for about ten years. Over months of 
experiment my warts were treated by numerous methods including 
freezing, cutting, blue dye applications and light treatments.  As 
the school year was nearing an end the doctor treated me with 
something he said he knew would work. He treated me with something 
called "DNCB"??? in which he scratched my back to make me allergic 
to this compound and then he administered a liquid to each of the 
warts.   Most amazingly, within 24 hours all warts literally 
disappeared. Not by falling off, but rather by receding and leaving 
no trace. It seemed almost miraculous.

Is anyone familiar with this experiment? I am just wondering what 
the compound was and if there are any side effects to this 
treatment.

Thank you for any help.
